You must be out of this world if you haven’t seen Heidi Klum’s ensemble for this year’s Halloween.

Everyone went gaga over her very scary, nightmarish costume. This year is going to be different.

Heidi Klum was determined. She wanted to go through 12 hours of processing of prosthetics, makeup and a lot of sitting around.

Wondering where she’s going ?

She’s attending her 20^th Annual Halloween at Cathedral New York which consists of a lot of big stars like Dylan Sprouse, Maluma, Ice T and many more.

Heidi Klum’s – Annual Halloween Party Preparation

Heidi Klum, who has 6.8 million followers, started with an Instagram post on Thursday morning with a photo of her sitting on a chair in front of fans and media.

Klum posted several photos from her hair being styled up until wearing those chunky, heavy prosthetics. She did it from the beginning of the process until the end.

This costume needed several different people working on her.

Aside from sitting, she readied herself with Amazon books.

Another Instagram post was her eating a bowl of pasta of which she was captioning “Pasta and prosthetics”.

In that photo, you would see that she was already wrapped up with exposed intestines showing up already and about to devour a mouthful of pasta. What a sport this gal is.

Two instances which brightened up her day was when both her husbands, reel and real ones, visited her.

Tim Gunn, her co-star in Project Runway, came to show his support. She continuously posted a lot of updates by photos and videos until it all came together.

As the time passed by, she looked more and more like an alien, very different from the glamourous and beautiful Heidi Klum we all know.

Mike Marino, head of Team Prorenfx, did really a really great job on her. If you look closely, even the veins and blood vessels were very particular.

Finally when the exposed brain was in place, this latex monster came into life but Klum was still on high spirits. She wrote “ Still here” with a wide opened eyes icon.

The Grand Entrance to Heidi Klum Halloween Party

The grand entrance couldn’t be any grander during the event than she and husband themselves, Tom Kaulitz.

Her husband became an astronaut for the night. Kaulitz’s helmet even featured shattered glass. To add to the effect, there was blood splatters over him.

Here’s the best part. Heidi Klum was transported by a glass wall trailer. There were some biohazard signs on it. She told reporters that this was an idea spanning from a science-fiction story.

The husband had another mission. He needed to look for a new planet because Earth is almost destroyed. He found her lurking around and thought that she might be able to give them useful information. So, she brought her here.

During her interview, she mentioned that she loved the process and was happy to have shared this to people who love Halloween. She wanted to share how these different artists do their living and how it all works in the movie industry.

Certainly, two thumbs up is not enough for this brave lady to have ventured 12 hours to look as a realistic alien!
